项目摘要

This research analytically and experimentally deals with the problem on development of micromechanical devices in the precision microparts manufacturing system. One of the mechanisms is the microhandling and feeding device such as a flexible finger constituted by a hooked bimorph type piezoelectric member with a rigid joint. The another one is the microactuating mechanism based on a lever and toggle-joint combination mechanism which is constituted by bimorph type piezo members connected by 4 elastic joints and 2 multilayer type piezo actuators. The actuator is available to precision workings, punching, hammering and press, or cramp of microparts for precision positioning. There are many merits, for example, it has variable output force-displacement characteristics by bending of the piezo members which are applied the independent voltage, respectively.The results obtained are as follows :1) Microhadling and feeding devices(a) Feeding and handling abilities are not influenced very much to its attaching posture, then a flexible constitution of the system is realizable.(b) When the axial direction of the fixed member approaches the feeding direction, the feeding force increases and the feeding distance decreases.(c) When the free member approaches perpendicularly to the feeding plane, the maximum free moved distance and the feeding distance increase.2) Micro actuating mechanism(a) The attaching angle of the lever member is available to set 90ﾟ.(b) There is the optimum pole combination of the applied voltages, The bending moment acted in the lever member makes to return the input point of the main actuator to the original position. The moment generated in the toggle-joint member makes to boost the bending.(c) There is the optimum voltage in which displacement of the input point does not cause. The miniature system is more and more realizable.

这项研究在分析和实验上处理了精确微型制造系统中微机械设备开发的问题。其中一种机制是微型和喂养装置，例如由带有刚性接头的挂钩双摩尔型压电构件构成的柔性手指。另一个是基于杠杆和切换 - 关节组合机制的微验证机制，该机制由Bimorph Type Piezo成员组成，由4个弹性关节和2个多层型压电驱动器连接。该执行器可用于精确工作，打孔，锤击和压制或限制微型的精确定位。例如，它具有许多优点，它具有分别应用独立电压的压电构件的弯曲，具有可变的输出力 - 位置特性。所获得的结果如下：1）微型和喂养设备（a）喂养和处理能力不会对其附着的姿势产生很大的影响，然后系统的灵活配置可实现。（b）当固定成员的轴向方向在喂食方向的最大进料距离时，馈送方向的最大距离会降低喂食距离（c），供给距离（c）降低了（c）。距离和进食距离增加。2）微作用机制（a）杠杆构件的附着角可用于设置90 ﾟ。（b）施加电压的最佳极点组合，在杠杆成员中作用的弯曲矩使得将主执行器的输入点返回到原始位置。在切换接头成员中生成的力矩可以增强弯曲。（c）有一个最佳电压不会导致输入点的位移。微型系统越来越可实现。
